SEECEFICATION forming part of Letters Patent No. 693,608, dated February 18, 1902.

Application filed September 6, 1901. Serial No. 74,501. (No model.)

To all wir/om, it may concern:

Be it known that I, FREDERICK KELLERS, a citizen of the United States, and a resident of Jersey City, Hudson county, New Jersey, have invented certain new and useful lmprovements in Brings, of which the following is a specification.

The object of my invention is to provide a bung which may be readily attached to and detached from a barrel, cask, or the like and which shall be strong, durable, and efficient; and to these ends the invention comprises a shell adapted to iit within a bung-hole and provided with a iange near its outer end and with arms near its inner' end, between which flange and arms a barrel stave or head may be clamped, and means for projecting` the arms from and withdrawing them into said shell for the purpose of fastening the bung in place or permitting its withdrawal from the bung-hole.

Reference is to be had to the accompanying drawings, forming part hereof, wherein- Figure lis a sectional view of a barrel provided with my improved bung. Fig. 2 is a sectional View of the bung, enlarged. Fig. 3 is an end view looking from the bottom of Fig. 2. Fig. 4 is a cross-section on the line 4: 4 in Fig. 2 looking in the direction of the arrows, and Fig. 5 is a perspective view of a wrench for operating the bung.

Similar numerals of reference indicate corresponding parts in the several views.

The numeral l in the drawings indicates a shell or body, which may be made of metal or other suitable material, and near its outer end said shell is provided with a flange 2, adapted to overlie the stave or head of a barrel or cask 3, by preference a gasket Il being interposed between the flange 2 and the stave or head. The shell l is also shown provided with a socket or recess l and with a bearing portion lb to receive a stem 5, whose squared or other-shaped head 5n is received in the socket l, as indicated in Fig. 2, so as to lie within the outer surface or end of the shell to protect said stem. Between the bearing portion lb and a flange 5 of stem 5 is shown a washer 5C to prevent leakage around the stem. Beneath the bearing portion lb the shell l is provided with a chamber lc and laterally-disposed openings ld, thro ugh which openings arms 6 are adapted to be projected. The arms 6 are suitably connected with the stem 5, so that by rotating the latter to the right or left said arms may be projected from or withdrawn into the shell l. I have shown a disk or plate 7 at the inner end of the shell l, adapted to rotate and provided with a centrally-disposed aperture to receive the squared or other-shaped end 5l of stem 5, a pin or other fastening 8 being provided to maintain the disk 7 upon the stem 5. The arms 6 are shown provided with pins 6, which pass through corresponding apertures in the disk 7 on opposite sides of the stem 5, and thus through the medium of the pins 6 and disk 7 the arms G are operatively connected with the stem 5. When the parts are in the position shown in Fig. et and the disk 7 is rotated by the stem 5 in the direction of the arrow, the pins 6 will push the arms 6 through the apertures 1d of shell 1 into the position shown in Figs. l, 2, and 3, and when the stem 5 is rotated in the reverse direction the arms 6 will be withdrawn into the shell. The upper outer edges 6b of the arms 6 are shown as beveled or inclined, so as to crowd under the stave or head of the barrel or cask.

The operation o f my device is as follows: To insert the bung in the bung-hole, the stem 5 is rotated, as by a suitable key or wrench 10, so as to withdraw the arms 6 into the shell l, and then the latter is pushed through the bung-hole, and the stem 5 is next rotated in the reverse direction, which causes the disk 7 to rotate, and thus the pins 6 push the arms 6 through shell l on the inner side of the stave or head, thus clamping the bung in position in the bung-hole, and the beveled or inclined edges 6b will serve to crowd the arms and flange 2 on opposite sides of the stave 0r head to make a tight iit. Vhen the bung is to be removed, the stem 5 is rotated so as to withdraw the arms 6 into shell 1, and the bung can then be removed from the hole. By having the outer surface of the flange 2 beveled or rounded or by having the iiange relatively thin the portion of the bung that projects beyond the stave or head will not interfere with the free use of the barrel and the bung will not he injured. The firm f1tting of the bung in the bung-hole prevents leakage around the shell, and Washer 5C serves to prevent leakage around the stem 5, although leakage at this point maybe otherwise provided against.

I do not limit my invention to the details of construction shown and described, they may be varied Without departing from the spirit thereof.

Hav-ing now described my invention, what I claim is- 1. Abungcomprisingashellhavingaflange near one end and a socket at the same end, a stem journaled in said shell and having its Operative end located in said socket, a pair of arms alined with openings in the opposed wall of the shell adapted to. be withdrawn VWithin the same and projected therefrom, a

disk with said arms for operating the latter, substantially as described.

2. Abungcoinprisingashellhaving a Hange near one end, a socket at the same end, a chamber near the other end and a bearing portion between said socket and chamber, a stem journaled in said bearing portion and having its operative end located in said socket and its opposite end in said chamber, a pair of arms located in said chamber, the Walls of said chamber having openingsfor the passage of said arms, a disk connected With said stem to be rotated thereby, and pins on opposite sides of said sternv connecting said disk and arms, substantially as described.
